Abstract (en)

[origin: WO2020234662A1] In a method for forming a spark over a spark gap, in particular for the inflammation of a flammable liquid for measuring its flame point, with the aid of a spark generator which has an ignition transformer (2) and comprises on the primary side of the ignition transformer (2) at least one DC voltage source (1) and on the secondary side of the ignition transformer (2) two electrodes (5) delimiting the spark gap (6) to be formed, wherein voltage pulses from the DC voltage source (1) are applied to the ignition transformer (2) on the primary side and generate ignition voltage pulses on the secondary side, the ignition transformer is operated in a first phase on the basis of the flyback converter principle and in a subsequent, second phase on the basis of the forward converter principle.
